We are going to continue our systematic method to diagnosing a pool heater by wanting at what to do temperature controlled heater when the mild inside the command pad on the top of your Sta-Rite pool and spa heater that is definitely labeled “service heater” is lit. (We're going to move forward with the assumption which you know every thing from phase 1.) This time you will need to eliminate the perimeters with the heater just before disconnecting electric power towards the heater to be able to read through the codes over the board attached on the topside. After getting rid of the edges, you will see the large topside that's still connected to the heater. Underneath the topside is usually a steel panel that retains the topside in position. Beneath this panel you will find two locking pins (cotter pins). Cautiously clear away the 2 pins and retail outlet them someplace secure right until reassembly. Gently remove the highest and turn it the wrong way up. You will see a light lit around the board you're searching at once you change the topside more than. The sunshine will likely be next to a code that's published on the board.

The very first code that you're going to see on the still left side of your board will be PS. This is actually the code for your stress swap. We protected the stress switch in segment one. If this mild is lit return to phase 1 and overview that section. If necessary adhere to the guidance to exchange the stress swap.

The next code you'll see within the board is HLS. Should you have a very controller within the program you have got to bypass it at this time. You must carefully disconnect the ability through the heater. Once you are confident the electrical power is disconnected, you must obtain and open up the high-voltage cupboard. This cabinet is a steel box in the course of the heater. Should you be looking on the cupboard, there is certainly generally a screw on the leading proper side. Loosen the screw as well as doorway will swing down towards you. You would like for being really careful when performing within this box and only accomplish that if you are absolutely sure that the electricity towards the heater is OFF.

You will have to bypass the firewall basic safety interface. To do this you'll need a small wire with stab-tab connectors. In case you have got a controller and it absolutely was thoroughly put in the wire could possibly have been remaining within the box by the tech who set up the controller. If not you will need to make this jumper wire. At this stage glimpse inside your owner's manual to track down the 2 appropriate pins to connect to. If you have a very controller or are employing a fireman's switch this is where your control need to be linked. If you use a controller and it is actually not related here, it could be the source of your respective complications and either have got a qualified tech right the challenge or correct it oneself.

You need to be mindful to not place the jumper wire over the energy terminals or you will wipe out your heater by burning up the digital method. Make use of your manual to find in which the fireman's change is meant being attached and carefully attach your jumper among these terminals. In the event you now activate the ability along with the heater performs without any difficulties, your challenge lies while in the controller or maybe the wiring visiting the controller. You will have to difficulty shoot this method.

In case you however possess the very same challenge using your heater. (“service heater” mild will come on), go away the jumper set up and verify the pump is on and that you might have great water flow. Ensure yet again with all your meter that the tension switch is not really cycling. It should read through being a useless shorter. (See phase just one) With fantastic drinking water flow confirmed along with the “service heater” mild on, your trouble may be amongst the thermo-regulators in the basic safety program.
